Reaction:
Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Axes of this channel must be re-referenced.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy:
Please inform the authorized personnel/service department. Check measuring circuit connectors for correct contacting.
Check encoder signals and replace the encoder if faults are found.
Monitoring can be switched off by setting MD36310 $MA_ENC_ZERO_MONITORING[n] to 100 (n = encoder number: 1,2).
Programm
continuation:
Switch control OFF - ON.
25001
Axis %1 hardware fault of passive encoder
Parameters:
%1 = Axis name, spindle number
Explanation:
The signals from the currently inactive position actual value encoder are missing, or they are not of the same phase, or
they exhibit grounding/short-circuit.
For PROFIdrive only:
MD36310 $MA_ENC_ZERO_MONITORING >100 replaces the existing PowerOn alarm by the Reset alarm 25011.
Reaction:
Alarm display.
Remedy:
Please inform the authorized personnel/service department. Check that correct contacts are established for the measuring
circuit connectors. Check encoder signals and replace the encoder if faults are found. Switch off monitoring with the
corresponding interface signal DB380x DBX1.5 / 1.6 = 0 (position measuring system 1/2 ).
The fault cause remains until the next power on
Monitoring can be switched off by setting MD36310 $MA_ENC_ZERO_MONITORING[n] to 100 (n = encoder number: 1,
2).
Programm
continuation:
Switch control OFF - ON.
25010
Axis %1 pollution of measuring system
Parameters:
%1 = Axis name, spindle number
Explanation:
The encoder used for position control sends a contamination signal (only in measuring systems with contamination signal).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
For PROFIdrive only:
MD36310 $MA_ENC_ZERO_MONITORING >100 returns the existing Reset alarm instead of the Power-on alarm 25000.
Reaction:
Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Axes of this channel must be re-referenced.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy:
Please inform the authorized personnel/service department. Check the measuring system in accordance with the
instructions given by the measuring device manufacturer.
Monitoring can be switched off by setting MD36310 $MA_ENC_ZERO_MONITORING[n] to 100 (n = encoder number:
1,2).
Programm
continuation:
Restart part program. Clear alarm with the RESET key in all channels of this mode group. Restart part program.
